Sichuan Earthquake

Updated: May 6, 2009

On the afternoon of May 12, 2008, a 7.9-magnitude earthquake hit Sichuan Province, a mountainous region in Western China, killing about 70,000 people and leaving over 18,000 missing. Over 15 million people lived in the affected area, including almost 4 million in the city of Chengdu.

Since the Tangshan earthquake in 1976, which killed over 240,000 people, China has required that new structures withstand major quakes. But the collapse of schools, hospitals and factories in several different areas around Sichuan has raised questions about how rigorously such codes have been enforced during China's recent, epic building boom.

In June 2008, low-lying areas in one of the towns most devastated by the earthquake were flooded as a torrent of water was released from a dangerous lake formed by landslides, dislodging wrecked homes, cars and corpses.

The surge of floodwater into the town, Beichuan, was part of an effort by engineers and soldiers to drain Tangjiashan, one of more than 30 so-called quake lakes that were formed by landslides. For weeks, the dam of rock and mud holding back the rising waters of the Jian River there had threatened to burst and flood towns and cities downstream that are home to 1.3 million people.

Another smaller earthquake struck the region in August 2008, damaging 258,000 homes and killing at least 32 people.

Thousands of the initial quake's victims were children crushed in shoddily built schools, inciting protests by parents. Local police harassed the protestors and the government criticized them. At least one human rights advocate who championed their cause was arrested.

The Chinese government has refused to release the number of students who died or their names. But one official report soon after the earthquake estimated that up to 10,000 students died in the collapse of 7,000 classrooms and dormitory rooms.

Reports emerged in July 2008 that local governments in the province had begun a coordinated campaign to buy the silence of angry parents whose children died during the earthquake.

Most parents whose children died took a payment of about $8,800 from the local government and a guarantee of a pension in exchange for silence.

In December 2008, government officials acknowledged in the most definitive report since the earthquake that many school buildings across the country are poorly constructed and that 20 percent of primary schools in one southwestern province may be unsafe.

In February 2009, a growing number of American and Chinese scientists suggested that the calamity was triggered by a four-year-old reservoir built close to the earthquake's geological fault line.

A Columbia University scientist who studied the quake has said that it may have been triggered by the weight of 320 million tons of water in the Zipingpu Reservoir less than a mile from a well-known major fault. His conclusions, presented to the American Geophysical Union in December, coincide with a new finding by Chinese geophysicists that the dam caused significant seismic changes before the earthquake.

By the first anniversary of the quake, mothers across the region were pregnant or giving birth again, aided by government medical teams dispensing fertility advice and reversing sterilizations. Because of China's policy limiting most families to having one child, the students who died were often their parents' only offspring. Officials say they hope a wave of births will help defuse the anger that many grieving parents harbor.

But the wounds have festered, in part because the Chinese government, wary of any challenge to its authoritarian rule, has muffled the parents and quashed public discussion of shoddy school construction. As the anniversary of the quake again focused attention on Sichuan, the government intensified its campaign to silence the parents and the media, resorting to harassment by police and threats of imprisonment.

The Sichuan government has explicitly prohibited media organizations from reporting on miscarriages by women in temporary housing camps. Some quake survivors say they fear that the miscarriages may have been caused by high levels of formaldehyde in the prefabricated housing.

A strong earthquake hit a rural part of China's far western Xinjiang region on Friday, killing three people, injuring dozens and destroying or damaging thousands of homes, the government and state media said.

A strong earthquake shook a sparsely populated area of western China late Tuesday, cutting telephone service and prompting residents to rush out of their homes, officials and media reports said. There were no immediate reports of injuries.

Ai Weiwei, a prominent artist and friend of political dissident Tan Zuoren, speaks about a police raid in the city of Chengdu in response to Mr. Tan's criticism of the government following the 2008 earthquake.

Engineers, construction workers and soldiers were racing Wednesday to relieve pressure on the dammed Bai He River in Sichuan Province that threatens millions of people who live downstream -- most of them survivors of the devastating May 12 earthquake.
